India will launch the third flight of its Geosynchronous Satellite Launch Vehicle Mk.III Wednesday, carrying the GSAT-29 satellite into orbit. Liftoff from the Second Launch Pad of the Satish Dhawan Space Centre is scheduled for 17:08 local time (11:38 UTC).
The Geosynchronous Satellite Launch Vehicle Mk.III, or GSLV Mk.III, is India’s newest and most powerful rocket. After making a suborbital demonstration launch in late 2014, the rocket made its first orbital mission last June when it deployed the GSAT-19 spacecraft.
Wednesday’s launch is designated D2, indicating that it is the rocket’s second developmental launch, however like last year’s flight its payload – GSAT-29 – is a fully operational satellite.
GSAT-29 is a high-throughput telecommunications satellite that will join the Indian National Satellite (INSAT) fleet in geostationary orbit.
The 3,423-kilogram (7,546-pound) spacecraft was built by the Indian Space Research Organisation (ISRO) and is based around the I-3K platform. ISRO will also operate the satellite and are conducting Wednesday’s launch that will place it into orbit.

After launch, GSAT-29 will position itself in geostationary orbit over the equator, at a longitude of 55 degrees East. The satellite’s communications payload consists of Ku and Ka-band ...
